The crest of the Yolla Bolly mountains defines this high-altitude landscape along the border of the Trinity National Forest and Mendocino National Forest. Mapped in the early 1980s, the area is characterized by the expansive Yolla Bolly-Middle Eel Wilderness, where drainage systems like the East Fork South Fork Trinity River and Beegum Creek carve deep canyons through ridges named after local figures and settlers. Human activity in this remote backcountry is represented by the Saddle Camp Forest Service Station, the historic Tomhead Mine, and various outposts such as Baker Camp and the Weston Ranch. The presence of features like Miners Cabin Spring and the Petijohn Trail highlights a legacy of prospecting and resource management in the high basins surrounding North Yolla Bolly Lake.
